使用 CodeIgniter 通过 Gmail 发送电子邮件时遇到问题？

Question

我正在尝试通过我的 Gmail 帐户在 codeigniter 中发送电子邮件。我当前的代码如下所示：

$config = Array(
     'protocol' => 'smtp',
     'smtp_host' => 'ssl://smtp.googlemail.com',
     'smtp_port' => 465,
     'smtp_user' => '[email protected]',
     'smtp_pass' => 'my_gmail_password',
     'mailtype'  => 'html',
     'charset'   => 'iso-8859-1'
);

$this->load->library('email', $config);
$this->email->set_newline("\r\n");
$this->email->from('[email protected]', 'Me');
$this->email->to("[email protected]");
$this->email->subject('A test email from CodeIgniter using Gmail');
$this->email->message("A test email from CodeIgniter using Gmail");

$this->email->send();

但是，这给了我以下错误：

Message: fsockopen() [function.fsockopen]: unable to connect to ssl://smtp.googlemail.com:465 (Connection timed out)
Filename: libraries/Email.php

Message: fwrite(): supplied argument is not a valid stream resource

Message: fgets(): supplied argument is not a valid stream resource

任何解决此问题的帮助将不胜感激！谢谢！

注意：我可以向您保证我的 Gmail 电子邮件和密码正确

Answer 1

该错误意味着您无法连接您输入的 SMTP 地址。

您应该使用：smtp.gmail.com

Answer 2

您可以下载“Shawn McCool”使用“Swift-Mailer”编写的漂亮的小火花包。
查看他的网站以获取安装说明

这是我使用 DRY 方法发送电子邮件的配置（需要 PHP 5.3.0！）。

配置
|--mailer[dot]php

$config['swift_email_server'] = 'ssl://smtp.googlemail.com';
$config['swift_email_port'] = 465;
$config['swift_email_username'] = '######';
$config['swift_email_password'] = '######';

库
|--MY_Email

    class MY_Email extends CI_Email {


    public function __construct(){
        parent::__construct();

    }
    /**
     * =========================================================================
     * Parse's html email templates - initalised via swift-mailer
     * 
     * @param mixed $data
     * @param string $template
     * @return html
     * 
     * ========================================================================= 
     */
    public function send_mail($data, $template){

        //Anonymous functions are available since PHP 5.3.0
        $callback = function ($matches) use ($data){
            return ( isset($data[$matches[1]]) ) 
               ? $data[$matches[1]] 
               : $matches[0];
        };

        //Finds any matches in brackets [] and replaces them with data passed via callback
        return preg_replace_callback(
                '/\[(.*?)\]/', 
                $callback, 
                read_file(EMAIL_TEMPLATES . $template));

    }


}

Email templates location defined in index.php
define('EMAIL_TEMPLATES', 'emailtemplates');

控制器
|--MY_Controller

    class MY_Controller extends MX_Controller{

        protected $user;

        protected $swiftMailer = NULL;


        public function __construct(){

            parent::__construct();


            $this->user =   ($this->session->userdata('uid'))
                        ?    Member::find($this->session->userdata('uid')) : array();

            $this->setup_profile();


           $this->form_validation->set_error_delimiters('<p class="form-error">', '</p>');


        }

        public function setup_profile(){
            $sections = array(
            'config'  => FALSE,
            'http_headers' => FALSE,
            'queries'  =>  FALSE,
            'memory_usage'  =>  FALSE
            );

            $this->output->set_profiler_sections($sections);

            if(ENVIRONMENT === 'development'){
                $this->output->enable_profiler(TRUE);
            }
        }

    protected function prep_email($data, $template){


            $message = 
            Swift_Message::newInstance('Type your heading here...')
              ->setFrom($data['email_address'])
              ->setTo(array($this->config->item('primary_email'), $data['email_address']))
              ->setBody( $this->email->send_mail($data, $template))
              ->setContentType('text/html');

            return ( $this->swiftMailer->send($message) );


     }


}
